(10) STPK (Factor to calculate proportional band) *
As this factor is so adjusted that the self-tuning result optimum to most controlled-objects is
obtained, do not change it.
This is the factor to adjust the proportional band to be calculated by the self-tuning function. The
larger the set value, the larger the proportional band thus calculated.
Setting range: 0 to 200
Factory set value:67
* Displayed when the self-tuning is provided.
(11) STIK (Factor to calculate integral time) *
As this factor is so adjusted that the self-tuning result optimum to most controlled-objects is
obtained, do not change it.
This is the factor to adjust the integral and derivative times to be calculated by the self-tuning function.
The larger the set value, the larger the integral and derivative times thus calculated.
Setting range: 0 to 200
Factory set value:16
* Displayed when the self-tuning is provided.
(12) ILIM (Integral time limiter)
This function is used to restrict the integral time calculated by the autotuning (AT) function during
heat/cool control.
If the integral time is limited by this function, the derivative time which is equal to 1/4 of the limited
integral time is automatically set.
Setting range: 4 to 3600 seconds
Factory set value: 3600 seconds (Z-1022 specification: 500 seconds)
• Displayed only for the instrument with the heat/cool control specification.
• Not displayed when the instrument is provided with the modbus communication
specification
(Z-1021 specification).
